PLA4231 User’s Guide

Your PLA4231 supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure 
wireless network. WPS is an industry standard specification, defined by the Wi-Fi Alliance.

WPS allows you to quickly set up a wireless network with strong security, without having to 
configure security settings manually. Each WPS connection works between two devices. Both 
devices must support WPS (check each device’s documentation to make sure). 

Depending on the devices you have, you can either press a button (on the device itself, or in its 
configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device 
to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two 
minutes to find another device that also has WPS activated. Then, the two devices connect and set 
up a secure network by themselves.

You can use the WPS button on the side panel of the PLA4231 to activate WPS.

Make sure the power LED and the WLAN LED are on (not blinking).

To copy wireless settings (SSID and wireless security key for example) from an access point (AP) or 
wireless router, press the WPS button for longer than five seconds and release it. The WLAN LED 
begins to blink.

To connect a WPS-enabled wireless client (such as your computer with a WPS-enabled wireless 
adapter) to the PLA4231 via Wi-Fi or to the existing wireless network through the PLA4231, press 
the WPS button for two or three seconds and release it. The WLAN LED begins to blink.

Press the WPS button on another WPS-enabled device within range of the PLA4231. 

The WLAN LED turns steady on when WPS was successful. The WLAN LED will be off for about ten 
seconds if WPS has failed, and comes on again. 

Note: You must activate WPS in the PLA4231 and in another wireless device within two 

minutes of each other.
